V UNITED JAMES MCCLUSKEY, OF NORTH BAY, ONTARIO, CANADA.

CATTLE-GUARD.

Specification of Letter Patent.-

Zl?atented i an. 5, 1969 Application filed December 13, 1907. Serial No. 406,342.

To all whom it may concern:

Be it known that 1, JAMES MoCLUsKnY, of the town of North Bay, in the district of Nipissing, in the Province of Ontario, Canada, coal merchant, have invented certain new and useful Improvements in Cattle- Guards, of which the following is the speciiication.

My invention relates to improvements in cattle guards, and the object of the invention is to provide a simple, cheap, and durable guard and one which it will not be necessary to remove for the purpose of track repairing or for any other purpose and it consists essentially of two platform members hinged together at their approaching ends, the outer member being pivotally supported in brackets at a point intermediate of its length and in proximity to the inner end thereof, the outer end of the member being suitably supported, the inner end of the inner member or the end nearest the crossing being supported on rollers journaled in suitable brackets as hereinafter more particularly described by the following specification.

Figure 1, is a perspective view of my cattle guard. Fig. 2, is a longitudinal section on line ab Fig. 1, showing the raised position of the guard by dotted lines. Fig. 3 is a section taken on line c-d of Fig. 2.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the platform comprising an outer and an inner member A and A The outer member A is formed by the longitudinal bars A and the cross slats A.

B is a rock shaft journaled in brackets B secured to one of the railway ties C.

B are bearings formed intermediately of the length of the bars A and in which the rock shaft is rigidly secured.

The rock shaft B is held from longitudinal movement by the split pins B The inner platform member A' is formed by the longitudinal bars A and intermediate bar A, the bars A being provided with an upward oflset A at the inner end or the end next the crossing, and the cross slats A being secured to the bars A and A.

The bars A of the outer member and the bars A and A of the inner member are hinged together by the cross hinge rod A".

D are brackets secured to the tie C which are susbtantially U-shaped in form and in which are journaled the rollers D on the journaled pins D.

E is a tail piece secured to the rock shaft B and E is a set screw inserted in the sleeper C and designed to limit the upward movement of the outer platform member A.

E are brackets which form a stop for member A, (one only of which is shown) to each side thereof and insure even movement thereof.

The reason for using two stops to limit the movement of the member A is for the purpose of preventing any side twist to the platform member A which might be caused by the animal stepping on to the platform to one side of the track and thereby strain the guard.

The bracket E forms a rigid stop for the member A. The tail piece is formed of s ring metal and serves to insure of the outer p atform member being swung down from the vertical position when the inner platform member is relieved of weight.

Having described the rinci al parts involved in my invention shal briefly describe the operation of the same. If cattle or other animals should attem t to cross the guard to stray u the track t ey must ste upon the inner p atform member which w' become depressed causing an outward and downward movement at the out end and thereby tilt the outer platform member into the osition indicated 1n the drawing by dotted ines thereby preventing the passage of the animal up the track. It will be seen also that when it is necessary to repair the track beneath the guard each member of the platform may be thrown u on its hinge A and the repairs accomplis ed without the removal of the guard.

From this description it will be seen that I have provided a guard of a very simple, cheap and durable construction being formed without any parts which are liable to get out of order.

What I claim as my invention is:

1. A cattle guard, comprising an outer and an inner platform member hinged together at their approaching ends, a support on which the outer member is pivoted intermediately of its length, and friction rollers on which the inner end of the inner member is supported as and for the urpose specified.

2. A catt e guard comprising ari outer platform member, a rock shaft journaled in inner end thereof, a friction roller journaled rackets secured to a tie a tail piece secured in brackets secured to a tie and on ,Which the to the rock shaft, a stop in the tie designed offset rests as and for the purpose specified.
